Summary: This study utilized environmental DNA (eDNA) metabarcoding to evaluate benthic communities at six salmon farms in British Columbia, Canada, comparing biotic signals associated with salmon farming impacts from two data sources. The research found that alpha diversity parameters decreased near fish cage edges and were negatively correlated with pore-water sulphide concentration. The study demonstrated the potential of eDNA metabarcoding for assessing the spatial extent of benthic impacts and developing local biotic indices related to organic enrichment.

Summary: The ecosystem approach to aquaculture (EAA) is a strategy for sustainable development, with a focus on environmental impact indicators. Research in salmon aquaculture literature primarily revolves around near-field benthic impact indicators. When evaluating indicators, scalability and alignment with environmental indicator criteria are essential considerations.

Summary: The study in Atlantic salmon aquaculture showed that different behavioral traits in copepodids affect the dispersion of lice and the infestation pressure on barriers, suggesting strong directional selection on copepodid swimming behavior by barriers. The findings emphasize the potential for barriers to slow louse adaptation by limiting access during periods of strong selection, with variations in seasonal and geographic strength of selection.

Summary: Construction waste generation is a significant issue globally, with New Zealand's construction industry responsible for a large portion of landfill waste. This study analyzed waste quantities from residential buildings to quantify waste generation rate and identified the impact of design decisions on waste generation, which can be applicable to timber-framed homes overseas.

Summary: This study examined the impact of salmon farming on several epibenthic suspension-feeders and identified potential molecular indicators of this impact. The results showed species-specific effects and differences in fatty acid profiles and host microbiome communities.

Summary: The study found that post-smolts of salmon do not disperse randomly during migration, but choose common migration pathways. They do not simply take advantage of currents to migrate, but actively swim to select routes.

Summary: This study used a biophysical model coupled with a water circulation model to simulate the dispersal of Atlantic salmon post-smolts in Passamaquoddy Bay. Different behaviors and swimming speeds were tested, and some behaviors were found to allow salmon to successfully leave the bay and match observation data reasonably well.

Summary: The study examined the distribution of marine meiofaunal nematodes and macrofauna in relation to environmental limitations, finding that selection processes were the primary driver for both assemblages with rare species playing a significant role. It was also discovered that the total number of species explained by non-selection processes was 27% higher in nematodes compared to macrofauna, highlighting the importance of a species-level approach in determining the contribution of selection and non-selection assembly processes.

Summary: By updating the salmon lice infestation model based on new insights, researchers found that salinity has the largest impact on infestation rates, while temperature and a potential temperature-salinity interaction effect may also play a role.

Summary: Aquaculture is a rapidly growing industry, and Integrated Multi-Trophic Aquaculture (IMTA) is a potential solution to minimize waste impact on ecosystems. However, there are challenges to implementing IMTA in Atlantic Salmon farms, such as scaling up extractive species and economic issues.

Summary: The study revealed that benthic marine food webs in estuarine Patagonian fjords are influenced by salmon farming activities, with isotopic analysis detecting the effects of food sources and aquaculture waste; high δN-15 values in sponge and encrusting coral may serve as ecological indicators for assessing environmental pollution.

Summary: This study develops a simple analytical model to investigate the dispersal of sea lice between two salmon farms. The arrival time distribution and cross-infection level of sea lice are calculated from the model. The study also finds that there is an intermediate interfarm spacing that maximizes the level of cross-infection, and increased temperatures lead to increased levels of cross-infection.

Summary: The analysis of benthic bacterial community structure has proven to be a powerful method for monitoring aquaculture disturbances in coastal environments. By studying the DNA of samples from various salmon-producing countries, core bacterial taxa have been identified that indicate different levels of aquaculture impact, regardless of specific conditions. This research provides valuable insights into the relationship between bacterial groups and benthic processes, contributing to a better understanding of ecosystem functioning in aquaculture sites.

Summary: This study examines the diversity of macroinvertebrates in typical and semi-arid tropical estuaries across multiple scales, identifying a non-random spatial pattern with higher beta diversity values at larger scales. In semi-arid tropical estuaries, richness difference plays a significant role in the rainy season, while species replacement is more prominent in the dry season. Overall, abundance difference is more important in structuring benthic macrofauna communities in both typical and semi-arid tropical estuaries across seasonal periods.
